ABSTRACT:
This invention provides a production method of a ceramic body that can use waste and defectives generated during a production process. The invention includes a dust removal step of removing dust below a predetermined particle size from granulated powder in a slurry, a molding step of molding the slurry containing granulated powder into a primary molded body, a cutting step of cutting the resulting primary molded body into a non-sintered molded body having a desired shape, a deflocculation step of deflocculating the dust removed in the dust removal step so that at least 50 wt % of particles having a particle size of not greater than 5 μm are contained, and mixing water to obtain a regenerated slurry, and a step of molding a non-sintered molded body from at least the regenerated slurry so obtained, and sintering it to obtain a ceramic body.
